JAMES HOLLIS MORRISON, OF DAYTON, OHIO.

DETACHABLE HINGE.

SPECIFICATION forming part of Letters Patent No. 616,952, dated January 3, 1899.

Application filed October 11, 1897. Serial No. 654,822. (No model.)

To cir/ZZ whom, t may concern:

Be it known that I, JAMES Ho'LLIs MORRI- soN, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Hinge, of which the following is a specification.

My invention relates to hinges, and partie ularly spring-hinges designed for use in connection with screen and similar doors; and the object in View is to provide a hinge adapted to be permanently attached to a door, shutter, or like structure, whereby the same is adapted to be dismounted with facility and without the removal of fastening devices, such as screws.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a hinge constructed in accordance with my invention applied in the operative position to a screen-door, a portion only of the latter with a contiguous portion of the frame or jamb being illustrated. Fig. 2 is a similar view of the hinge and the keeper or attaching-plate disengaged. Fig. 3 is a perspective View of another modified form of hinge constructed substantially like that shown in Figs. 1 and 2. Fig. Ilis a similar View showing the parts disconnected. Fig. 5 is a rear view, partly broken away, of the keeper.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the drawings I have illustrated a few only of the modifications of which my invention is susceptible, the essential feature of the same being that the hinge, of which the swinging leaf may be constructed of any preferred form to suit the use for which it is designed, is connected with a stationary leaf having an interlocking connection with a fixed keeper or attaching-plate adapted for permanent attachment to a frame or jamb, while the stationary leaf is permanently attached to the swinging leaf of the hinge and is adapted to be mounted upon and disengaged from the said keeper or attaching-plate bya simple longitudinal movement and without the loosening of screws or similar fastening devices, as in the ordinary construction, the permanently-fixed keeper of the stationary leaf being of such shape as to project but slightly from the face of the frame or jamb, whereby when the door to which the hinge is secured is not in use the keeper forms an unobjectionable attachment.

In one embodiment of my invention, which is illustrated in Figs. l and 2, the swinging leaf 1 and thehinge-pin 2, by which the alined eyes or knuckles of the hinge-leaves are connected, (and, if desired, a door-closer consisting of a spring 3,) are carried by the frame 4 of a door, shutter, or similar structure, while attached to the frame or jamb 6 of said door or equivalent swinging structure is a fixed keeper or attaching-plate 7, adapted to be secured 'in place by screws S and constructed for the reception of the stationary hinge leaf or member 9, said leaf 9 having eyes 10, which register with the eyes 1l on the swinging leaf for permanent connection by the above-mentioned hinge-pin. The keeper is longitudinally slotted to form a seat 12, which in length and depth corres pond with the length and thickness of the fiat plate constituting the stationary leaf of the hinge, whereby said leaf is adapted to be fitted snugly into the seat by a lateral or horizontal movement. The stationary leaf is of a width greater than the seat and is provided with terminal notches 13 of equal width with the keeper and adapted to engage the end Walls of the seat when after tting the leaf into the keeper it is moved longitudinally or parallel with the seat, toward either of the ends thereof, said end walls forming positive stops to limit the movements of the leaf parallel with the'seat. Obviously only one notch of the stationary leaf can be engaged with the contiguous end wall of the seat'at one time; but it is equally obvious that either notch may be engaged with the adjacent end wall of the seat, according to the direction in which the hinge is moved after the seating of the plate in the keeper. This feature of the construction provides for applying the hinge to either a right or left hand door, or, in other words, provides a reversible hinge, which in this art is desirable as adapting hinges suitable for either right or left hand doors to be con- IOO structed from the same patterns or in the same molds, and thus relieving a dealer of the necessity of carrying a double stock in the same line of goods.

From the above description it will be seen that to interlock the stationary leaf with the keeper it is necessary simply to insert the former into the seat of the latter and then allow the weight of the hinge or of the door or other structure to which said hinge is iiXed to settle or drop by gravity a sufficient distance to engage the lower notch of said plate with stop formed by the end wall of the seat. Vith this relative arrangement of parts the stationary hinge -leaves are firmly locked against lateral displacement, whereas when it is desired to dismount the door it is necessary only to raise the same sufficiently to disengage said lower notches from the contiguous walls of the seats and then withdraw the stationary leaves from the seats.

In the above-disclosed form of my invention the stationary hinge-leaves and the keepers have an interlocking engagement, whereby the former is adapted to be dismounted without detaching the latter from the frame or jamb and adapting the door or other structure provided with the improved hinges to be mounted and dismounted Without loss of time and without the use of tools. Furthermore, in Figs. 3 to 5, inclusive, I have shown another construction of the hinge embodying my invention,wherein the attaching-plate 7 d and leaf 9d are constructed substantially similar to those shown in Figs. l and 2, in that they consist, respectively, of a keeper having a seat 12d and a plate to fit in said seat and provided with notches 13d for engaging stops on the keeper. The'outer edge of the leaf 9d is recessed and is undercut at the ends'of the recess to form the notches 13, ln said modiiied construction, however, the notches 13d, while formed near the extremities of the plate or near the upper and lower corners thereof, are inturned or inwardly open, (instead of outwardly open, as in the said construction shown in Figs. l and 2,) and the keeper is fitted at an intermediate point with a fixed block 12e, the opposite ends of which form stops for engagement by said seats 13d. In this construction l have also shown additional locking devices, consisting of lugs or projections 20, carried by the plate near its outer edge and extending perpendicular to the plane thereof, said lugs being adapted to bear against the contiguous or rear edge of the keeper when the leaf is moved longitudinally to engage one of the seats 13d with the stop ou the keeper, the front wall of the keeper being horizontally grooved, as shown at 20a, to allow said studs or projections to be inserted, and said grooves being preferably tapered toward their rear ends. These tapered grooves, of which the larger ends are at the inner edge of the keeper, facilitate the introduction of the lugs 20, and said grooves are reduced toward the outer edge of the keeper to a width approximately equal with that of the lugs, whereby a comparatively slight longitudinal movement of the plate forming the stationary leaf of the hinge will be sufficient to engage the lugs with the stop formed by said rear edge of the keeper and also engage one of the inwardlyfacing notches or seats 13l with the stop formed by the contiguous end of the block 12. It will'be understood, furthermore, that in practice various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what l claim isa l. A hinge having a stationary leaf, in combination with a longitudinally-slotted keeper forming a seat, the hinge-leaf being removably fltted in the seat and terminally constructed to interlock with the seat by an independent longitudinal movement, substantially as specified.

2. A hinge having a stationary leaf, in combination with a keeper having an open-sided seat, the hinge-leaf being removably fitted in the seat and provided with seats or notches opening in opposite directions to engage contiguous stops on the keeper when the removable member is moved longitudinally, substantially as specified.

3. A hinge having a stationary leaf, in combination with a keeper having an open-sided seat, the hinge-leaf being removably fitted in the seat and provided with inwardly opening or facing seats or notches to engage contiguous stops on the keeper when the removable member is moved longitudinally, substantially as specified.

4. A hinge having a stationary leaf, in combination with a keeper having an open-sided seat provided with an intermediate fixed block, the hinge-leaf being removably fitted in the seat and provided with inwardly-opening seats or notches, for engagement with opposite ends of the said fixed block, when the removable member is moved longitudinally, substantially as specied.

5. A hinge having a stationary leaf, in combination with'a keeper having an open-sided IOO IIO

seat, the said hinge-leaf being removably fitted in the seat, and being provided with lugs or projections extending perpendicular to the plane of the leaf, to engage contiguous stops on the keeper when the removable member is moved longitudinally, substantially as specified.

6. A hinge having a stationary leaf, in combination with a keeper having an open-sided seat, the said hinge-leaf being removably fitted in the seat and being provided with lugs or projections extending perpendicular to the plane of the leaf, to engage contiguous stops on the keeper when the removable member is moved longitudinally, and the keeper being transversely grooved in one of its walls to allow said lugs or projections to pass through the seat, substantially as specified.

7. A hinge having a stationary leaf, in oombination with a keeper having an open-sided seat, the said hinge-leaf being removably iitted in the seat and provided with lugs or projections extending perpendicular to the plane of the leaf, to engage contiguous stops on the keeper When the removable member is moved longitudinally, and said keeper being provided in one wall of its seat With transverse tapered grooves to allow said lugs or projec- .tions to pass through the seat, those ends of the grooves contiguous to said stops being approximately equal in size to the said lugs or projections, substantially as specied.
